VODACOM ****S PEOPLE BY STILL DEBITING THEIR ACCOUNTS AFTER BEING CANCELLED

I have written to Vodacom, phoned them, went to their head office but cannot solve my problems, seems like they just like to make money out of people and cannot solve-their problems, I have cancelled all my contracts except 1 which is a data base contract but they still debit my account with three other contracts which has expired are they a bunch of ****** or what can I call them
